DEMOUNTABLE RIM.

Specification of Letters Patent. Patented Oct, 13, 1914.

Application filed May 23, 1914. 'serial No. 840,612.

To all whom it may concern: 7

Be it known that I, LOUIS M. HovERsoN, a citizen of the. United States,residing at Brandon, in the county of Minnehaha and, State of SouthDakota, have invented certain new and useful Improvements in DemountableRims, of which the following is' a specification. v

i This invention comprehends certain new and useful improvements indemountable rims and has for its primary object to provide a device ofthis character which will be of extremely simple construction and willbe formed in such manner that the parts may be readily secured in properposition to support a tire upon the rim of a wheel upon which thisdeniountable rim is employed.

.A further object of the invention is to provide a demountable rim whichwill be constructedin such manner that the side flanges will serve tosupport the tire in proper position and clamp the same upon the rimpositioned ,upon the felly of the Wheel.

A further object of the invention is to provide improved and novel sideflanges 'havinglocking ribs for engagement with the side locking edgesof the ribs extending outwardly from the ,same, whereby the side flangeswill be prevented from moving out p of position after theturnbuckles,.employed for connecting the opposite ends of said flanges,have been tightened.

This invention has for a further object to generally improve andsimplify the construction and operationof. devices of this character andincrease the efficiency thereof without materially increasing the costof the same.

With these and other objects in view as will become more apparent as thedescription proceeds, the invention consists in certam novel features ofconstruction, combination and arrangement of parts as Wlll behereinafter more fully described and claimed.

For a complete understanding of my vention, reference is to be had, tothe following description and accompanying drawings, in -Which- Figure 1is a side elevation of a wheel, employing my improved formof-demountable rim, Fig. 2 is an enlarged detail section on the line 22of Fig. 1, and Fig. 3 .is a

detail sectional view through one of the turn-buckles and rods connectedby the same for tightening the removable side flanges.

Referring in detail to the drawings by numerals, 1 designates the hub, 2the spokes, and 3 the felly of a wheel upon which 1 have shownpositioned my improved 'de mountable rim comprising principally a re-.movable rim or plate 4 formed ofa suitable sheet metal and having theopposite edges directed outwardly to form locking flanges 5 having theirinner edges 6 beveled, the purpose of which will presently appear. A-suitable tire '7 may be positioned upon the rim 4 with the flanges 8 ofsaid tire projecting outwardly. The tire 7 is secured in position bymeans of the removable side flanges 9 having inwardly directed portions10 for engagement between the flanges 8 and the main portion of the tire7, the up-.

per faces 11 of said inwardly directed portions 10 beingconcaved tocorrespond to the curvature of the tire 7 and to form suitable supportsfor the same. The side flanges 9, as will be readily understood, are inthe form of transvcrselysplit rings and have the rods 12 extendedthrough the same to reinforce SaldSlClB flanges and also serve asconnecting means for the ends of said side flanges, the extremities ofsaid rods "12 be ing projected'beyond the ends of the'fianges I andthreaded to receive the turn-buckles 13,

locking flanges 5 of the rim-4 to prevent outward movementof said sideflanges 9.

The outer edges 15 of the' locking ribs 14.- are' beveled to correspondwith the inner edges 6 of the locking flanges 5, whereby said sideflanges 9 will be, forced inwardly as the ends of said side flanges aredrawn together. It will also be seen that by providing the lockingflanges 5 and the locking ribs 14: with the opposed inclined faces, the

1 side' flanges 9 will be caused to securely clampthe tire 7 in positionupon the rim 4 and itawill further be readily seen that outs wardmovement of the flanges 8 of-lthe tire 7 will be prevented by thelocking r'ibs 14 which are positioned, between the ends of said flanges8 and the lockingflangesfi.

Further, it will be evident that after the turn-buckles 13 have beentightened, it will be impossible for the side flanges 9 to work out ofposition until the turn-buckles 13 are again loosened.

. While I have shown and described the preferred embodiment of myinvention, it will be understood that minor changes in the details ofconstruction, combination and arrangement of parts may be made withoutdeparting from the spirit and scope of the -mvention-as claimed, orsacrifleting any of the advantages thereof.

- What is claimed is 1.- A device of the class described comprisingthecombination with a flanged tire and felly; of a rim positioned upon saidtelly, removable side'flanges having portions ii engaged against theouter faces of the flanges of the tire to force the latter against therim, locking flanges carried by said rim, locking ribs carried by saidremovable side flanges and engaged with said locking 25 flanges toprevent outward movement of flanges thereof to force said outwardlydirected flanges against the rim, the outer faces of said inwardlydirected portions being concave to conform to the curvature of the mainportion of the tire, means for tightening the side flanges andpreventing movement thereof independently of the tire and rim, and meanscarried by said side flanges and said rim to prevent outward movement ofsald side flanges.

3. A device of the class described comprising the combination with atire, rim and felly; of removable side flanges positioned upon. saidrim, the flanges of said tire being engaged upon said rim, said sideflanges having inwardly directed portions for engagement with. the outerfaces of the flanges of said tire to press said tire flanges against therim, said rim having locking flanges formed along its opposite edgeswith inclined inner faces, said side flanges being provided with lockingribs having inclined faces for en gagement with the inclined faces ofsaid locking flanges to prevent outward movement of said side flanges,said removable side flanges being transversely split, and

means for drawing together the opposite 0 ends of said side flanges toclamp the latter upon the rim.

In testimony whereof I aflix my signature in presence of two witnesses.
